OIL BURNER.

Application filed May 21,

My invention relates to oil burners.

It has special reference to means and methods for developing a combustible mixture of air and oil.

The invention is specially directed to means for delivering a-irand oil under proper compression thru a common conductor to a dis-' charge point; to means for imparting spiral activity to the oil and air mixture for delivering thru a common conductor after the fuel mixture is discharged from conductor and to means for conducting an auxiliary supply of air under proper compression to a point of discharge adjacent to discharge from the combined air and oil conductor; to means related to the auxiliary air conductor for inducing spiral activity to the air after it is discharged from said auxiliaryair conductor and includin a relationing of the mechanism for inducing such spiral activity respectively of the combined air and oil body and the auxiliary air supply to effect the necessary functioning relationship between such mixture elements as to promote high degree of combustible efficiency; and

the invention alsoincludcs means for igniting'the fuel mixture.

Referring to the drawings: J

Figure 1 is a vertical sectional view of my invention of the structure and relative ar rangement of the parts. A

Figure 2 is a front end view of the structure illustrated in Figure l.

Figure 3 is a vertical sectional view of a conductor means for, an air and oil mixture and including the disclosure of details with respect to parts and relative arrangement thereof, especially in the matter of assemblage and proper relative functioning".

Figure 4 is-a front end View of same subject matter that is disclosed in Figure 3, including a diagrammatic dotted line showing with respect to relative positioning of parts rearwardly of the front end of said structure disclosed in Figure 3.

I am aware of the fact that prior patent art exemplifies an instance or instances wherein oil and air have been delivered thru a common conductor as instanced by a structure wherein a common air and oil conductor is provided and wherein a common fanis 1923. Serial No. 640,556.

housed within such common conductor at a point intermediate-the entry and discharge ways of said conductor, but in the instance of the structure here presented an exteriorly applled pressure is employed for the oil and air wherein no fan action or mixin mechanism is interposed between inlet an outlet of the air and oil conductor.

I am also aware vof the fact that both atent and practically applied art disc ose means employed in connection with oil burners for producing spiral activity to fuel oil to discharge thru a conductor but I am not familiar with any art disclosure or practical art exemplification of the particular or special means herein disclosed forinducing such centrifugal action of oil and air mixture parts and I am not aware of any art disclosure of co-related means for eflecting acentering of an oil or oil and air and an auxiliary air supply at a point in advance of discharge ways for said combustible ingreclients.

Referring to the drawings:

i 10 is an air and oil conductor, the rear end of which is designed to beconnected with an air supply and including means (not shown) v for inducing proper projectional pressure upon the air and-discharged into the conductor pipe.

11 is an-oil inlet pipe, the same to be con-' nected-to the proper oil supply and including means (not.shown) for inducing the proper degree of pressure to function in connection with the pressure upon the air supply to promote co-mingling of said air and oil within the forward reach of conductor or mixing pipe.

12 is a head or closure cap member, the same being centrally perforated as at 13 and may be fashioned in'conca-ve-inwardly faced I form as at 14C to promote deflection of fuel to outlet perforation13f 15 is a block member intervening between closure cap member 12 and conductor member 10, the same being fashioned with screw threads conformatory to screw threads on the capand conductor member to facilitate joining of parts as shown. Block member 15 is arranged in off center relationship with respect to conductor member 10 and is provided with the interior longitudinal bore 16 which. may, as shown, be of larger diameter than that of conductor pipe 10.

17 is a spirally fashioned member preferably loosely mounted in the further end of block member 15 and in abutting relationship with closure member 12.

18 is aeoil spring member interposed between the rear end of spiral member 17 and the off set wall portion of block member. The structure herein which includes the block member interposed between conductor pipe and the head members; the detachable or segregable spiral member and spring member serviceable in holding spiral member in proper relationship to the head member and the discharge opening therein are preferably employed for the purpose of conven ience in manufacture but it will be under-- stood that the spiral member may be permanently or differently related to the end conductor member without departing from the purpose or principle of; my invention.

19 refers generally to a deflector for an auxiliary air blast that is discharged into and thru a cylindrical casing or shell 20. The structure of this deflector includes a hub or sleeve member 21 designed to fit over and to be supported upon block member 15 and there is provided screw attaching means as 22 whereby said hub or sleeve member may be fixed in the desired position upon said block member; it also includes plural" curved members 23 arranged at spaced relatidnship about the hub member and coin-- cidentally fashioned to effect the common centering of the air blast passing therefrom to a point in advance of tubular member 20. The fashioning of members 23 is designed to be such that the outer edges liein contact with inner; wall of tubular member 20 when deflector is in working relationship with said tube and the block member. A functioning relationship is adapted to be established between the deflector member 19 and spiral 17 whereby a common centering point may be established for the discharge of fuel ingredients from tubular member 20 and member 15, and to that end deflector 19 is made adjustable upon and lengthwise of said 'block member so that by trial the .proper relative arrangement of these functioning parts may be established whereby the maximum of 'mi'xin efiiciency may be established to the end of ighest degree of combustible etficieney.

In connection with the auxiliary air supgas supply which discharges adjacent to the fuel discharge oint; also, I have provided an -.-.lectric sparlfing point 25 its terminal arranged adjacent discharge of the commercial gas, but as these features are the subject of claim in connection with another and separate application, it is not deemed necessary to further describe. the same herein.

26 is a thermo control member-adapted to function under the influence of heat and advance of heat within the combustion chamber, with one of the burners is associated to effect control of the running of a motor employed in the general burner organization, but as this feature is made the subject of a separate application it will not be further described herein. I have shown herein my preferred form of the development of my invention however, the form and arrangement of parts may be modified to accord with convenience in manufacture or for special uses to which the device may be put without departing from the spirit of the invention herein exemplified and as special points used in the appended claim. While I have shown separate communicating ways for air and oil to the common conductor for both fuel ingredients and assumed the application of the proper compression means, nevertheless, it'is within my conception that a common compression means may be employed as in the instance of the disclosed structure in my prior patent on liquid fuel atomizer No. 1,451,798, dated, April 17, 1923, upon an application filed October 8, 1920.'

C'et screws 27 are fashioned with relation to the deflector members 23 in a manner to maintain same in a fixed position when once they have been set for proper and efficient cooperation with the discharging fuel mixture.

Relative to the fashioning of the spiral 17 and the deflector member 23, it will be' noticed that the spiral 17 is adapted to direct the discharged fuel mixture in one Y direction while the deflector 23 spirals the air blast in the opposite direction. The purpose of opposing the action of the air blast and fuel mixture is to increase atomization by more completely breaking up the fuel and air particles by having the air blast oppose, rather than follow, the action of the fuel mixture.

Likewise, the velocity of the particles is increased and, therefore, the speed of combustion, with a result that the complete burning of the fuel mixture will take place within a comparatively small space.

Similarly, the length of the fire, as well as the efficiency of the fire, may be regulated by proper movement ,of theadjustable deflector member. The proper setting of the defleetormember having once been found, said member may be positively located b means of the set screws 27.

What claim is In a device of the class described, in combination, a conductor member for a fluid mixture, a nozzle adapted to retard the discharge of the fuel mixture, a block between the nozzle and conductor having a bore concentric with the nozzle opening, a loosely mounted spiral member within the bore adjacent the nozzle, adapted to project the fuel mixture through the nozzle with a spiral movement, an air blast casing concentric with said nozzle, and a plurality of deflector members therein carried on a sleeve mounted on said block, and means for adjustably securing sleeve to said block, said deflectors contacting with said casing to direct the air blast in a spiral direction opposite the spiral of the fuel mixture whereby adjustment of the sleeve adjusts the distance of contact from the nozzle of the two respective spirals.

In testimony whereof I afiix my signature.
